Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 8,&QY%8pX  
Type: Double Bounces -wn(J5NnR  
The '****' denotes a possible internal focus ?1/wl;=fm  
RMS is the RMS spot radius on axis at the primary wavelength. j*@EJ"Gm>  
RMS values of 0.00 indicate that an accurate RMS F$>^pw  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is W$?Bsz)
